1953-99-7 Usage
General Description
3,4,5,6-Tetrachlorophthalonitrile, also known as PCAN, is a white to pale yellow crystalline compound with the chemical formula C8Cl4N2. It is a potent herbicide and is used to control the growth of broadleaf weeds in various agricultural settings. PCAN acts by inhibiting photosynthesis in the target plants, leading to their stunted growth and eventual death. However, the chemical also poses a risk to non-target organisms and the environment due to its high persistence and potential to bioaccumulate. As a result, its use is heavily regulated, and it is classified as a restricted use pesticide in many countries. Additionally, PCAN is also considered to be a potential human carcinogen, and exposure to it can cause skin and eye irritation, respiratory issues, and other health effects.
Check Digit Verification of cas no
The CAS Registry Mumber 1953-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,5 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1953-99:
(6*1)+(5*9)+(4*5)+(3*3)+(2*9)+(1*9)=107
107 % 10 = 7
So 1953-99-7 is a valid CAS Registry Number.

FORMATION OF AROMATIC NITRILES BY DIRECT REPLACEMENT OF THE NITRO GROUPS OF DINITROTETRACHLOROBENZENES
Milner, David J.
, p. 479 - 484 (2007/10/02)
Direct replacement of nitro by cyano groups has been effected by treatment of the dinitrotetrachlorobenzenes in refluxing chloroform with aqueous cyanide ion in the presence of a phase transfer catalyst.
